LIGHTWEIGHT CONCRETE WITH LOW THERMAL CONDUCTIVITY
A concrete includes cement; effective water; aggregates (G1) having a maximum size of 20 mm and a real density (ρ1) of 450 to 1200 kg/m3; optionally aggregates (G2) having a maximum size of 4 mm and a real density (ρ2), such, that the real density (ρ) of the mixture (G1)+(G2) is comprised from 450 to 1200 kg/m3 with 1/ρ=m1/(ρ1)+m2/(ρ2) m1 and m2 respectively being the mass fractions of (G1) and (G2); the concrete having (a) a density in the fresh state of 800 to 1500 kg/m3, (b) a Weffective/Beq ratio varying from 0.19 to 0.60, (c) a quantity of effective water varying from 100 to 320 litres per cubic metre of fresh concrete, (d) quantity of cement and optionally of additions greater than or equal to 200 kilograms per cubic metre of fresh concrete; (e) a volume of paste greater than or equal to 300 l/m3 of fresh concrete and a volume of air of 1 to 16%.
